WATCH-BOW PLIERS.

SPECIFICATION forming part of Letters Patent No. 562,998, dated June 30,1896.

Application filed February 26,1896. Serial No. 580,791. (No model.)

To all whom it may concern:

Be it known that I, HENRY W. WILDT, a citizen of the United States,residing at Alexandria, in the county of Alexandria and State inwatch-bow pliers; and the object is to provide a simplified and improvedtool for the purpose of inserting and detaching a watchbow, and also tofit the bow in its bearings or sockets.

In my Letters Patent No. 514,7 99, dated February 13, 1894, is shown anddescribed watch-bow pliers comprising two members having curved jawswith hooked ends, the members being independently pivoted in upper andlower bearing-plates, in the center or middle of which is mounted thestud carrying the hooked bar. This construction and arrangement of thecoacting parts serve the purpose well and expeditiously, but the cost ofmaking the implements is greater than expected, and I therefore have, inmy present invention, simplified and cheapened the production and haveimproved the construction by making the implement more compact anddurable.

I have fully and clearly illustrated my improvements in the accompanyingdrawings, forming a part of this specification, and wherein Figure 1 isa view in perspective of the complete implement. Fig. 2 is a centrallongitudinal section thereof, showing one handle and jaw in side view.Fig. 3 is a plan view of the left-hand handle and jaw. Fig. 4 is abottom plan view of the right-hand handle and jaw. Fig. 5 is a plan viewof the tool, showing its application and use.

The tool is comprised of two members, each made of a single piece ofmetal, composing the handle 1 and jaw 2. Each member in generalconstruction is the same, except that the curves and contours arereversed in direction, substantially as shown. The members are unitedand held pivoted or jointed together bya knuckle-joint and strong hollowpivotal pin or stud 1 formed on one of the members, and which studengages in a bearing-aperture 2 formed in the knuckle-piece of the othermember, substantially as shown. The bearing-stud 1 is formed with anaperture 8, and extends through knuckle-piece and is intended to take inand retain the holding-pin of the post which carries the hooked bar, ashereinafter specified.

In the inner face of each handle, closely adjacent to the knuckle-joint,is formed a socket 4c, constituting seats for the ends of aspreading-sprin g 5,which spreads the handles apart and closes the jawsto hold the members in position for immediate and convenient applicationto the bow of the watch. In the inner face of each handle is formed arecess or seat 6, the seats being oppositely disposed and elongatedlongitudinally of the handles, as shown, the purpose being to affordmeans for grasping the bow to compress it when required.

The jaws 2 are projected straight forward and lie when in closedposition parallel with each other, as shown in the drawings, and areformed on their ends with upturned or outturned hooks 7 7 to take in andhold the bow-ring adjacent to the ends, as shown in Fig. 5 of thedrawings, so that when the handles are moved together the jaws will bespread apart or opened and move the adjacent ends of the bow apart inconvenient position to insert them into the bearings or to dislodge themtherefrom. To resist the endwise pressure and maintain the hooks of thejaw in their engagement with the bow, a hooked bar 8 is provided, thebow being held by the hook when the tool is'applied thereto, asindicated in the drawings, and the tool is thus held against backward orlongitudinal displacement. The hooked bar 8 is preferably provided withscrew-threads 9 on its body or stem, and is adjustably held in theuprights 10 10 of a post 11, having alining apertures therein, andbetween the uprights on the threaded bar is an adjusting-nut 12, wherebythe bar may be adjusted longitudinally to suit the engagement of thehook to any sized bow. The post 11 is formed with a downward-extendingstem or pin 13, having a threaded socket 14 therein, in which afastening-screw 15 is fitted, which, being screwed down until theflanged head rests on the surface of the tool, holds the post firmly inposition.

The application or use of my improved device is as follows: To insert abow in the stem, the hooked ends of the jaws are inserted in the ringadjacent to the ends thereof, with the rear of the bow engaged in thehook of the adjustable bar, and then by compressing the handles the bowis opened, and, being placed with the ends in alinement with thebearings in the stem, when by releasing the pressure on the handles thebow by its resiliency moves the ends into the bearings. Should the bowrequire additional seat in the bearings, thering is placed between thehandles, seated in the recesses 6, and pressed inward until the ends areseated as desired. To detach the bow, the tool is applied as stated andthe ring then opened until free from its bearings.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The watch-bow pliers, comprising the two members united by aknuckle-joint and hollow pivotal stud and formed with parallel c jawsterminating in upward-turned hooked ends, a post provided with a hollowthreaded stem to engage in the hollow pivotal stud of the members, aholding-screw in the threaded stem of the post, a threaded hooked rodslidingly arranged in the said post, and an adjusting-nut on thethreaded rod, as specified.

2. A watch-bow pliers, comprising the handle and jaw members 1, 2,united by a knuckle-joint and a hollow pivotal stud 1 the said jawsbeing parallel with each other and formed with hooked ends, aspreadingspring seated in the handles adjacent to the joint thereof,seats 6 in the handles, a post 11 formed with a hollow threaded stem 13to fit in the hollow pivot and having uprights provided with aliningapertures, a holdingscrew to engage in the hollow threaded stem, ahooked bar, having a threaded stem and arranged in the uprights of thesaid post, and an adjusting-nut on the threaded stem of the hooked bar,between the uprights on the post, substantially as described.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
